Sodium Metaphosphate is an important inorganic phosphate, commonly used as a pH regulator and buffering agent in industrial and chemical fields. It can effectively adjust and stabilize pH values, avoid abrupt changes in acidity and alkalinity, and maintain stable system performance. It features excellent buffering capacity, which improves process controllability, enhances product stability, and protects sensitive raw materials and reactions from pH fluctuations. It is widely used in food processing, water treatment, detergent formulation and chemical production that require precise pH control.

Nickel Sulfate has multiple hydrated forms, presenting greenish-yellow, blue or green crystals varying with hydration degree. It is widely used in nickel electroplating to coat iron and copper surfaces, delivering uniform and durable metal coatings. It also acts as a catalyst in chemical reactions and a textile mordant to enhance dye fixation and color fastness. Additionally, it serves as a coating material for special industrial parts, suitable for surface treatment and anti-corrosion applications.
